Introduction
My lab focuses on the intracellular regulatory mechanism of ion transport proteins functionally expressed in exocrine glands, such as salivary glands, and epithelial cells. I'd like to move my research forward by comprehensively using electrophysiological, molecular and cell biological methods and organ and tissue perfusion methods. For example, one theme is to identify membrane transport proteins (i.e.,ion channels and transporters) that exist in the parotid gland of ruminants such as bovines. The proteins enable amazing membrane transport (particularly of bicarbonate ions and phosphate ions). Another theme is the identification of intracellular regulatory proteins that control the membrane transport proteins. In addition to these studies, I hope to contribute to the understanding and treatment of human diseases caused by abnormalities of structure and function of ion channels and transporters (i.e., channelopathies and transportopathy) through basic studies on cell physiology using porcine tracheal epithelium and ciliated epithelial cells.
List of current research topics

| Self introduction |
I've been interested in general physiology and cell physiology since my school days, and I've studied the functions and intracellular regulatory mechanisms of ion channels and transporters, which are important for substance transport in epithelial tissues and epithelial cells. |
